Spermatozoon (\u00e7o\u011fulu: spermatozoa) ya da k\u0131sa ad\u0131yla Sperm h\u00fccresi, erkek bireylere ait \u00fcreme h\u00fccresidir.<\/p>\n
Testislerde olu\u015fan bu h\u00fccrelerin \u00fcretimi ergenlik d\u00f6neminde ba\u015flar. Ba\u015f k\u0131sm\u0131nda d\u00f6llenme s\u0131ras\u0131nda yumurtaya aktaraca\u011f\u0131 kal\u0131tsal bilgi (DNA) ta\u015f\u0131r. Kuyru\u011fu vard\u0131r ve hareketlidr. Bir \u00e7iftle\u015fme s\u0131ras\u0131nda 300 milyon sperm sal\u0131n\u0131r. Ancak yumurtay\u0131 yaln\u0131zca tek bir sperm d\u00f6lleyebilir. Bir sperm bir yumurta h\u00fccresine ula\u015ft\u0131\u011f\u0131nda, yumurtaya girmek i\u00e7in kuyru\u011funu d\u0131\u015far\u0131da b\u0131rak\u0131p, yumurta zar\u0131ndan ge\u00e7erek kal\u0131tsal bilgileri yumurtaya ula\u015ft\u0131rm\u0131\u015f olur. Spermler yo\u011fun k\u0131vamda bir s\u0131v\u0131n\u0131n i\u00e7inde bulunurlar. Bu s\u0131v\u0131n\u0131n ismi meni ya da ersuyu denir.<\/p>\n
Spermin ba\u015f\u0131 bir h\u00fccre \u00e7ekirde\u011fi gibidir. \u0130\u00e7inde kal\u0131tsal bilgileri bulundurur. \u0130\u00e7inde genetik \u015fifre ve DNA vard\u0131r. Bunlar yumurtaya ge\u00e7ti\u011fi zaman kromozomlar \u00e7o\u011fal\u0131r ve buna g\u00f6re cinsiyet belirlenir. Kromozomlar tek halde olu\u015fup, \u00e7ifte b\u00f6l\u00fcn\u00fcrler ve b\u00f6l\u00fcnd\u00fckleri zaman do\u011facak bireyin cinsiyeti belirlenir. E\u011fer kromozomlar XX \u015feklinde ise bireyin cinsiyeti di\u015fi olur, e\u011fer XY ise bireyin cinsiyeti erkek olur.Ancak bazi istisnalar da vardir.Mesela XXY , X0 , vs gibi hastalikli bireyler de olusabilir.<\/p>\n","protected":false},"excerpt":{"rendered":"
